Definition

Molluscum contagiosum is an infection of the skin.

Molluscum contagiosum is caused by a specific virus. The virus can be spread from:

    
  • Direct skin to skin contact with an infected person
  • Shared items, such as towels or wrestling mats
  • One part of a person's body to another area
  • Risk Factors

    Factors that may increase your risk of getting molluscum contagiosum include:

        
  • Weakened immune system, especially in people with HIV infection
  • Poor hygiene
  • Overcrowded conditions
  • Sexual contact
  • Having other skin conditions, such as atopic dermatitis
  • Symptoms

    Molluscum contagiosum may cause:

        
  • Small, dome-shaped bumps with dimpling in center
  • Painless, but may be itchy or tender

  • White or waxy substance in center of lesion
  • Usually multiple lesions in groups
  • Face, trunk, arms, and legs are common sites in children

    Diagnosis

    Diagnosis is usually made based on the lesion appearance. Sometimes a biopsy will be taken to rule out other conditions. A biopsy is the removal of a small sample of the area.

    Treatment

    Molluscum contagiosum usually goes away on its own within six months to two years without any treatment. For people with HIV infection, the lesions usually persist and spread indefinitely. Your doctor may recommend the removal of some lesions to prevent the spread of the infection or to avoid infecting others.

    Lesion may be removed by one of the following:

        
  • Cryotherapy—freezing of the lesion
  • Curettage—cutting out lesion
  • Laser surgery—burning of the lesion
  • Topical therapy—destruction of the lesion with a variety of chemicals
  • Prevention

    To reduce your chances of getting molluscum contagiosum, avoid any contact with an infected person.

    If you are contagious, avoid any personal contact with others, contact sports, or sharing personal items.
